UV-B induced immunomodulation: a health risk

Identification of UV-B-induced microRNAs in wheat.

MicroRNAs (miRNAs) play critical roles in post-transcriptional gene regulation and act as important endogenous regulators to various stressors. Ultraviolet-B (UV-B) radiation is a major factor influencing crop growth and development. In this study, we isolated a novel wheat miRNA, named Tae-miR6000, and confirmed its expression diversity after UV-B treatments. Additionally, using the Northern b...

UV-B induced fibrillization of crystallin protein mixtures

Environmental factors, mainly oxidative stress and exposure to sunlight, induce the oxidation, cross-linking, cleavage, and deamination of crystallin proteins, resulting in their aggregation and, ultimately, cataract formation. Various denaturants have been used to initiate the aggregation of crystallin proteins in vitro. All of these regimens, however, are obviously far from replicating condit...

A UV-B-specific signaling component orchestrates plant UV protection.

UV-B radiation in sunlight has diverse effects on humans, animals, plants, and microorganisms. UV-B can cause damage to molecules and cells, and consequently organisms need to protect against and repair UV damage to survive in sunlight. In plants, low nondamaging levels of UV-B stimulate transcription of genes involved in UV-protective responses. However, remarkably little is known about the un...

Stress-induced immunomodulation: implications for infectious diseases?

THERE IS NOW SIGNIFICANT LITERAture showing that psychological stress can down-regulate various aspects of the cellular immune response. It is also established that communication between the central nervous system and the immune system occurs through bidirectional signals linking the nervous, endocrine, and immune systems. Psychological stressors affect the immune system by disrupting these net...
